Bias cut fitted sheets

Abstract

A fitted sheet that fits on mattresses of various thicknesses by having a construction that is elastic along the side edges of the sheet. The sheet includes an insert extending from one side portion of the sheet to another. The insert is placed such that the side edge of the fitted sheet is formed by the insert. This allows the fitted sheet to fit more elastically over the corner of a mattress.

1 . A fitted sheet made of at least one textile material comprising:
 a body having a concave shape and including:
 a top panel with four edges, and four side panels with at least two ends, wherein a respective side panel is adjacent one of the four edges; and 
 at least one triangular insert including two insert side edges and a bottom edge, wherein each of the insert side edges is attached to a respective end of two adjacent side panels; 
   wherein a corner fold of the fitted sheet extends from the insert bottom edge to a point on the body.   
   
   
       2 . The fitted sheet of  claim 1 , wherein the at least one triangular insert is four triangular inserts. 
   
   
       3 . The fitted sheet of  claim 1 , wherein the body includes side folds where the top panel meets the side panels, and
 an apex of the triangular insert is positioned where the corner fold meets the side folds.   
   
   
       4 . The fitted sheet of  claim 1 , wherein the sheet is elongated, the top panel is rectangular and two of the side panels are short, the short side panels being opposite one another. 
   
   
       5 . The fitted sheet of  claim 4 , wherein the at least one triangular insert is two triangular inserts, the two triangular inserts each being attached to an end of one of the short side panels. 
   
   
       6 . The fitted sheet of  claim 1 , wherein the textile material of the at least one triangular insert includes a bias direction angled with respect to both the direction of the warp and the direction of the weft of the textile material. 
   
   
       7 . The fitted sheet of  claim 6 , wherein the bias direction of the at least one triangular insert is substantially aligned with the corner fold that extends from the bottom edge of the triangular insert to the point on the body. 
   
   
       8 . The fitted sheet of  claim 6 , wherein the bias direction of the at least one triangular insert is within 30 degrees of the corner fold that extends from the bottom edge of the triangular insert to the point on the body. 
   
   
       9 . A fitted sheet made of a textile material comprising:
 a body having a concave shape and including:
 a top panel with four edges, and at least one side panel having at least two ends, wherein the side panel is adjacent at least one of the four edges; and 
 at least one insert including two insert side edges and a bottom edge, wherein a first one of the insert side edges is connected to one of side panel ends and a second one of the insert side edges is connected to an other of the side panel ends; 
   wherein a corner fold of the fitted sheet extends from the bottom edge to a point on the body of the fitted sheet, and the insert is made of a textile material having a weft and a warp that are orientated at an angle with respect to the corner fold.   
   
   
       10 . The fitted sheet of  claim 9  wherein the at least one insert is two inserts,
 the at least one side panel is two side panels,   each insert is connected to both of the side panels along its respective insert side edges, and   two corner folds of the fitted sheet extend from the bottom edge of each insert to separate points on the body of the fitted sheet.   
   
   
       11 . The fitted sheet of  claim 9  wherein each insert includes a top edge adjacent the top panel of the body. 
   
   
       12 . The fitted sheet of  claim 10  wherein the two side panels are longer than the two inserts. 
   
   
       13 . The fitted sheet of  claim 9  wherein the textile material of the insert section includes a bias direction angled between the direction of the warp and the direction of the weft of the textile material. 
   
   
       14 . The fitted sheet of  claim 13  wherein the bias direction of the insert section is substantially aligned with the corner fold. 
   
   
       15 . The fitted sheet of  claim 13  wherein the bias direction of the insert section is within 30 degrees of the corner fold that extends from the bottom to the body of the fitted sheet.
